To all whom it. may concern: Y

Be it known that PERRY l5. Beam-nuns citizen of thevUnited States, residing.at 880 East .First South, Salt Lake Gity, in the county of-SaltLakc and Stateof lltah has invented certain new and useful lmproveinentsin Hater-Measuring Devices, of which the following is aspecification.

This invention relates to a device for accurately measuringthe flow of Water and its object is to provide an improved structure of this character adapted to bedispesed at any desired point in a canal, ditch or the like, of any size, shape or character of lmnks and capable of accurately indicatingthe flow of ,Water therethrough.

A further object of the ,inventionis-to provide a device of the characterabmffi vSe 1 9F61 constructed in such manner as to adapt it to serve asa head gate as .wellas a measuring device.

Afurther object of theinvention is to providea device of the character above set forth constructed insuch manner as to adapt it to measure water in a channel having a very slight grade.

As this description proceeds it will be seen. that the device forming the subject matter thereof may be manufactured at a moderate cost and-in such manner that it will not be subject to drying and swelling, warping and cracking, Withresultant leakage and that consequently the expense of maintenance of the sameisredjuced to a minimum.

In the accompanying drawing,

Figure 1 is a perspective view of a co1nbined head gate and measuring device constructed in accordance with the invention.

Fig. 2-is a vertical, sectionaliviewth ough the gate thereof, and

Fig. 3 is a horizontal, sectional view through the gate thereof.

In the drawing u designates a metal box which may be of any desired shape in cross section and the several parts of which are securely riveted together as indicated at q to provide a structure that will be water tight except for the orifice or inlet opening a and the discharge opening I). m indicates a lap joint made in the metal Z of the box by which the entire vertical portion of the box u is fastened together. The box comprises a bottom '22, secured by a joint 0 to the side walls.

To aid in stiffening and reinforcing the structure angle irons k are secured thereto weeten ess? eerthe gate so be cease-pa ne sci-es d i clin d alas Po t 9 lo g a their are t ov. ;-.te,e charge pipe 79.

This is highly'desirablje because metal is not subject to the sh' w ll ng and wa ring at ha e been f nd so gll-y 0, the use of wooden parts for 'tl'ns'pur "G id .ire e iic h -s de si course or travel. The'lo discha unshin ithe a vrt. 12aii ii:it Y. complete submersion "of the openlng a A pair of galvanized iron pipes of the same length are soldered together and held vertically alongside of the box at by means of strips Z These pipes extend from a point level with the center of the inlet opening a; to the top of the box and they carry floats V and W which rise and fall in the pipes with the rise and fall of the water levels on the outside and inside of the box, respectively. The water pressure outside of the box u is communicated to the float V through the bottom of said pipe, the bottom of said pipe being open, while the water pressure inside of the box is communicated to the float W through an opening 2 formed in the side wall of the box to the pipe :1: in

V such a position as to secure a continuous submersionof the orifice and the free passage of the water of the canal into the pipe carrying the float V. The height of the box is made to correspond to the depth of the canal. lVith the gate 0 closed the water will stand at the same level inside thebox as in the canal outside of the box and the tops of the wires y will be at the same elevation.

As the gate 0 is raised and varying quantities of water allowed to pass through discharge pipe 39 and thence througha ditch or elsewhere, there results a corresponding difference of level in the water surface inside of the boxand in the canal and this diflerence is indicated by thedifl'erence in eleva tion of the tops. of the wires y. This difference of water level is due to the loss of head in passing through the inlet openin a.

' aving once ascertained the rate of flow during any given difierence in elevation of the tops ofthe wires 3/, it follows that a rating-table may be had which in conjunction with the wires y will render it possible to determine the amount of water passing the gate at any given. time.

i It will, therefore, be observed that in addition to providing a measuring means as herein set forth my improved structure serves the function of a head gate and that by its use the entire flow of Water may be controlled or shut off at will.

From the foregoing description it will be seen that simple and eflicient means are herein provided for accomplishing the objects of the invention but while the elements shown are well adapted to serve the purposes for which they are intended it is to be understood that the invention not limited to the precise construction set forth but in cludes within its purview such changes as come within the spirit of the appended claims.

Having described my invention what I claim is 1. The combination with a receptacle of a pair of stilling wells, one of which wells is in communication with the water outside of the receptacle and the other of which is in communication with the water on the inside of the receptacle, a float in each well, a rigid upstanding rod carried by each float, said rods lying side'by side and cooperating indicating members carried directly by said rods and movable therewith in respect to each other.

2. A device of the character described comprising a compartment, an inlet opening thereto, an outlet opening therefrom, a gage comprising a pair of elements one of which is actuated under the influence of the water within the compartment and the other of which is actuated under the influence of the water outside of said compartment, the difference in movement of said elements indicating the difference in the water levels inside and outside of said compartment, respectively, and a gate for controlling the passage of water from said compartment through the outlet openings.

3. A structure as recited in claim 2 wherein the lowest point of said outlet opening is at least as high as the highest point of the inlet opening.

In testimony whereof I affix my signature in the presenceof two witnesses.
